The author-actress went on to describer her struggle via Instagram story.

“I could already be in a depression,” she revealed. “I’m planning on eating my placenta, but I’m also anticipating a major emotional dive. I think that it’s chemical. I think people don’t talk about it enough.”

She added: “Because having a baby is the scariest f—ing thing that could happen to a woman.”

Mollen said after giving birth to her 3-year-old son Sid she told “everybody that it felt like I was coming off of cocaine.”

“It was just like the craziest come down of my life,” she added. “Maybe because I know what to expect this time, it’s almost happening sooner, like I’m already going through the motions of [this] insane life changing experience.”

She encouraged fans to be “hyper-vigilant” about their emotions after giving birth.

“You’ll be shocked at how fast you’ll wake up one day and be in the darkest place,” she said. “The only way your kid is going to be healthy and happy is if you are healthy and happy. So, make that the priority.”

In April, the author-actress and the Orange Is the New Black star, 39, announced their second pregnancy.
